GAS-BURNER.

SPECIFICATION formingpart of Letters vPatent N o. 690,471, dated January 7, 1902.

Application filed January 30, 1901. Serial No. 45,342. (No model .l

To all whom, t may concern:

Be it known that I, WALTER J. SMART, of the borough of Brooklyn, city and State of New York, have invented a certain new and useful Improvementin Gas-Burners, ot' which the following is a specification.

This invention relates to gas-burners, and particularly to that type or class thereof known as inverted gas-burners, and has for an object to provide improved means for delivering a maximum of air to those portions of the flame where combustion can most advantageously occur, whereby increased luminosity or brilliancy is attained.

Referring to the drawings which accompany the following specification and illustrate an embodiment of my present invention, Figure l is an elevation of such a burner. Fig. 2 is a view of the burner as it appears when looked at from the under side in Fig. l, and Fig. 3 is a central lengthwise section.

Similar characters of reference designate corresponding parts in all figures.

In the present illustrated embodiment of this invention it is shown applied to an annular burner-body B. The space between the walls 2 and 3 of this annular body communicates with the gas-supply, in the present instance by means of the passages through hollow arms b, (any appropriate number.) As shown, these arms b extend from a socket C, by which the burner may be attached to a gas-outlet toward, and are connected with a ring C', which may be secured gas-tight to the burner-body B in any suitable way. A baille-plate D, which in the present instance consists of a perforated ring or any other device designed for the purpose of distributing the gas uniformly through the gas-space, may be inserted therein.

The gas-outlet from the burner-body B may consist, as shown, of a number of openings 4, extending through the base thereof and yielding a flame when in use annular in form and curving upward exteriorly of the body. The air-supply to the inside of the flame takes place downward in this form of inverted burner through the axial opening 5 of the annular burner-body. An air-deflector 6 is arranged adjacent to the openings 4. With the form of burner-bod y shown an effective shape for this deiiector is circular, and preferably the inner wall 2 of the burner-body is chamfered off or beveled from within outwardly toward the openings 4 (see 7) to facilitate the passage of air to the base of the flame as it is directed outwardly by the surface of the defiector 6.

For the purpose of securing as uniform a distribution as possible of air for combustion to all portions of the annular flame this deflector 6 may be supported in position from the burner-body B by means of an air-distributer 8, here shown to be cylindrical in form and of less diameter than the diameter of the axial opening through the burner-body. The perforations in this airdistributer, in View of the function it performs, are spaced substantially uniformly throughout the shell thereof, while the distributer at its lower eX- tremity is attached to the deflector 6, adjacent to the innervedge of the latter. An outwardly-extending flange 9 connects the airdistributer to the burner-body B. This flange 9 is shown perforated also to admit air into the annular space between the distributer and theinner wall 2 of the burner-body, while a shoulder 10 may be provided upon the burner-body to assist in the correctpositioning of the parts in place. A

To secure an efficient delivery of air to the flame at points adjacent to and beyond the base thereof, there may be a second air-dis- Y tributer attached to the deflector 6, which may consist, as herein illustrated, of a cupshaped distributer E, comprising a perforated Hange dependent from the outer edge of the deflector 6 and a perforated disk l2 at the lower portion of this dependent flange.

Combined and organized in the manner illustrated and described, a burner of the foregoing-characterized type is provided with means for directing the incoming air to those portions of the flame at which it is most effective in increasing the brilliancy of the light, as well as means for dividing up and rendering uniform the distribution not only to those portions, but the surplus air for combustion to other portions of the llame.

IOO

deflector, and an air-distributer on the other side thereof disposed adjacent to the outer edge of the deector.

2. An annular defiector combined With a cylindrical air-distributer on one side of the defleetor, and a cup-shaped air-distributer on the other side thereof consisting of a perforated liange extending from the outer edge of the deliector and a perforated disk at the end of the flange.

3. An annular deector combined with a cylindrical air-distributer on one side of the dedector, a perforated flange extending from the cylindrical air-distributer and a cupshaped air-distributer disposed on the opposite side of the air-deflector and consist-ing of a perforated flange extending from the outer edge of the deector and a perforated disk at the end of the flange.

4. In combination with an annularbnrnerbody, an annular air-defiector, a cylindrical air-distributer on one side of said deector, and an air-distributer on the other side thereof disposed adjacent to the outer edge of the deiector.

5. The combination With an ann nlar burnerbody having its inner Wall chamt'ered or beveled adjacent to the burner-outlet, of an airde Hector located centrally of the burner-body and in proximity to the chamfered portion of the Wall of the body and an air-dstributer.

6. In combination with an annular burnerbody having its inner Wall ehamfered or beveled adjacent to the burner-outlet, of an airdeeetor, an air-distributer on one side of the defiector and an air-distributer on the other side thereof.

7. In combination with an annular burnerbody having its inner Wall ehamfered or beveled adjacentV to the burner-outlet, of an airdeieetor, a cylindrical air-distributer on one side of the defleotor and a cup-shaped air-distributer on the other side thereof.

S. In combination with an annular burnerbody having its inner Wall chainfered or beveled adjacent to the burner-outlet, of an annular air-defieetor, a Cylindrical air-distributer on one side of the deiieetor, a cup-shaped air-distributer on the other side thereof, and a iange connecting the cylindrical air-distributer with the burner-body.

Intestimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.

WALTER J. SMART.
